Due

Tuesday, April 12 at 11:59 PM

Description

We have covered the basics of networking in iOS apps, as well as the different elements from UIKit. This project will combine both concepts, and result in an app that displays photos pulled from Instagram via its public API.

In this project, you will be parsing JSON objects to display the photos and additional relevant information that Instagram users have posted and shared. The purpose of this assignment is to familarize you with creating UICollectionViews, and have you practice the iOS Networking knowledge you learned to use a popular company's API.

Instructions

Create a Photo Social Network App

• Required
  • Photo.swift - the model which represents a single Photo object
    • You only need to implement the init
  • InstagramAPI.swift - the object which connects with the Instagram API
    • You must implement the loadPhotos method
  • PhotosCollectionViewController.swift - Collection View of Photos
    • One photo per cell
    • You must implement any necessary delegate methods
    • You must implement loadImageForCell
  • Tapping a cell takes you to a photo-specific view with the following:
    • UIImage of the Photo (from the URL)
    • UILabels to display:
      • The poster's username
      • The date posted
      • The number of Likes on the photo
    • A Heart button to Like the photo
      • The Heart button should change to indicate whether the photo has been liked or not
• Optional
  • Toggle between different feeds (Popular, Photos from Berkeley, etc.)
    • Suggested: Tabbed Application
  • Enable ability to "push" to Instagram's servers (e.g. A Like that you make in your app is reflected on Instagram)
    • Note: Requires facilitating OAuth with Instagram's API
  • Add a Search tab so that you can search for Users, Hashtags, etc. and retrieve the relevant images
  • Optimize the app's performance
    • Add GCD to use background threads for smoother loading
    • Add a NSCache for the images
